tion of the various parts separately.

Be it known that I, HENRY BAB'rn, of the city of Cincinnati, in thecounty of Hamilton and State of Ohio, have invented a certain new anduseful Improvement in Stop-Cylinder Printing-Presses, of which thefollowing is a specification My invention relates to mechanism forstopping and starting the cylinder of a stop-cylinder press, whosecircumference is greater than the way described by the bed-plate; forconof the type; and 0, Fig. 4, theimpressioncylinder. The feed-board Fis provided with purpose of receiving a motion on and 0d the dischargingit therefrom; for distributing the ink; and for other purposes, as willmore perfectly appear in the description hereto annexed.

In the drawing, Figure 1 represents a side elevation of the whole press.Fig. 2 is a longitudinal section, looking toward the side frame S. It isintended to show the stop and starting mechanism, the ink-fountain, themotion of the dip-roller, and the motion of the ink-fountain roller. Forthe purpose of being bed B. The type-bedB runs on rollers fitted derside of the bed B, and which is driven by rack D, Fig. 1,which 18secured tothe groundtop view of one corner of the press. It shows theposition of the different cams on the main shaft. Fig. 4 is a part of alongitudinal section through the center line of the press, on a largerscale. It represents the complete cylinder with all its details, hefeed-board, ers, and the paper-discharge arrangement. Fig. 5 is acomplete cross-section of the press,

I.--The Motion of the Type Bed and Cylinder. F, Fig. 1, is thefeed-board B, the bed trunnions, which rest in bearings placed on F j lthe vibrating arms A, A. A, and A, for the impression-cylinder, in amanner hereinafter described. The impression-cylinder is held in; ibearings which are fitted to the side frames f i 1 S and S, Figs. 1 and5, and. is operated at Fig. 4, which driven by the rack B, fastened tothe type-g to the ribs X X, Figf5,and is operated by the rack Z, Fig. 4,which is bolted to the unthe traveling wheelT. The traveling wheel Tgears at the same time into the stationary frame F. By means of the rodY, Fig. 1,.the axis of the wheel T is connected with'the .9

and is driven by the pinion The pinion P v is keyed to the shaft K, towhich the motive 1 power is applied. u Thedriving-shaft K has. i to beturned in direction of the arrow,and the pinion P fixed to it will drivethe. wheel I v of the crank, which is formed by inserting-the motion ofwheel I will cause an alternative T.

As far as the description now reaches, the motion of the bed B and ofthe impressioncylinder 0 of the press does not differ from L, the oneend of the connecting-rod N, Fig.2, is attached by means of thewrist-pin g. The other end of the connecting-rod N is held by the hanger0 through the pin it. The hanger O oscillates upon the pin 2 attached tothe frame.

part of my invention consi ts.

The drawing shows all the different parts of my press in the positionsthey have at that moment when the type-bed B commences to that thestraight line, which bisects the sinus versus of the angle of vibrationof the lower arm of the lever L, and which passes through the axis ofthe main shaft J, bisectsthesinns versus of the angle of vibration ofthe hanger 0 also. To the connecting rod N the two friction-rollers kand l are attached. The cam Q acts upon the roller k, and the cam U uponthe roller 1, Fig. 2. The cams are firmly secured to the shaft J, so asto rotate with the same; they have such a shape and their position is soadjusted as, through the medium of the connecting rod N, the doublelever L, and the teeth f e and e, to start and stop the cylinder 0,

0 cl have changed their positions, the cylinder is stopped bya mechanismhereafter described and is held at rest when the type-bed B is about tomake its return movement. As soon as the bed B commences a new stroke inthe direction of the arrow the cylinder 0 is started and turns with thebed again, but another part ofthe cylinder namely, the surface a bcylinder are in the position in which they are drawn, and the bed isgoing to move in the direction indicated by the arrow, the cylinder isstarted by the cams and caused to turn in .snaeiasthet ne-hedntatiT otgear into so as to print, successively, three, four, or more sheets ofthe full capacity of the type-bed during one revolution of the cylinder,and while they are entirely in gear when the tooth 0 leaves the space fthen the rackR continues to drive the cylinder, and the lever L, withthe space f, is caused by the cams to move backward to the extremeposition f 9, Fig. Fig. 2, on the ends of the connecting-rod N, At thesame time the cylinder (J has arrest the shock caused by the tooth e inthe cylinder striking against the tooth fin the lever L.

II. 'Thc rllechanr'srn for Stopping and Starting the Cylinder.

v For the purpose ofstopping and starting the impression-cylinder twice,or oftener, during one revolution, the cylinder is provided out of gear.When the double-armed lever-L arrives at its mean position, eg, the camswill cause the same to. stop there and to hold the cylinder stationary.A little time after the cylinder is stopped, the type-bed B has finishedits forward stroke, and while it'is running back, the cylinder 0 iscaused, bythe cams, to remain stationary, and as the teeth are-cuting-surfaces and two stops, the impressioniylinder O is provlded withthe two stoppingmd-starting teeth 6 and c, Fig. 4. They are lotattacheddirectly to the cylinder, but they re firmly secured to thespur-wheel W, Fig. which is fastened to the cylinder 0. One fter theother the teeth 6 and e gear into the as follows: At the moment whenthe'bed and I cylinder will be analogous to aw y at the part of thewheel \Vwhich faces the rack B, while the cylinder is held stationarythe bed B can freely pass under the cylinder. When the bed B has arrivedat its extreme backward position, from where I started to follow itsmotion, and in which position it is drawn, the double armed lever L isin its startingrposition also, but the cylinder 0 I find one-half turnedaround, and the teeth 0 e and the printing-surfaces a b and 0 d inchanged places. But as the two halves of the cylinder are symmetrical,the position of the the position in which it is drawn. While the bed isrunning forward and backward the next time, the cams and U will startand operate upon the second half of the cylinder 0 in the same manner asduring the first forward and backward strokes of the bed. Mystop-and-start mechanism has the advantage over many others designedbefore, of having less joints, and the relative positions of the doublelever L and the hanger O, as described above, cause it to operate withperfect accuracy. For the purpose of observing conveniently the actionof the stop-and-start teeth f e and e, I have provided the side frame Swith an opening or window, V, Figs. 1 and 4, which assists me inadjusting these important parts very finely and perfectly.

III.-T he Paper Feeding and Delivery Arrangemeat.

The arms A A A and A, Figs. 1 and 2, upon which the feed-board F rests,vibrate on pins inserted in the side frames S and S. The arm A is madewith the arms at and n, Fig. 1, in one piece. Over the end of the arm ata projection of the side frame S is provided, with an adjusting screw,as, Fig.1, by which the end position of the feed-board F, in regard tothe impression-cylinder U, can be regulated. A double armed or elbowlever, s, Fig. 1, is fastened inside of the side frame S to the. shaftor axle t; A hole bored through the side frame S serves as bearin g forthe shaft t. The shorter arm 1" of the elbow-lever s and the arm n ofthe threearmed lever A m n are connected by the rod upon which a springis wound. One end of this spring presses against the guide q throughwhich the rod p goes, and which is fastened to the side frame S '5 theother end of the spring acts upon the head 0 of the rod 1),-consequently the spring will push the feed boardF so far toward theimpression-cylinder U as the setscrew as over the arm will allow. To thelonger arm 98 of the lever-elbow s the cam-rod c islattached. At itslower end the cam-rod v is provided with a long. hole, in which it isguided by shaft 2 in one way, while between the collar-y and the camw,it is guided the other way. The cam w is fastened to thecam-shaft z,and acts upon the roller 2). It has such a shape, and. such a position,that itqcauses,

through the roller 1:, the cam-rode, the elbow-;

levers s, the rod 1), and A, the feedboardF to move, at correct times,off of the impression-cylinder 0, holds it in the position furthest fromthe cylinder, while the paper is put onto it, and moves it upto thecylinder again, bynieans of spring 12, a little before the cylinder isstarted. I The cam-shaft z receives a rotary motion from thecontinuation z of the main shaft, J, through the miter wheels 16 and 17,Fig. 1. The continuation e, which lies in line with the main shaft J, isprovided with the crank 18, I by 3 Y which it is coupled by means of theconnecting;

piece 100 to H of on the main shaft wrist pin the wheel I,

and its continuation z.

inder, and gears into secured to the pulley-shaft 3. The shaft 3 is heldin bearings in the side frames Sand S,

and carries two or more pulleys 4 4, which slide on the shaft 3, and maybe tightened at any place required, Figs. 1, 4, and 5. The arms 5 5,which form at each end a fork, are slipped on to the shaft 3 the sametime with the pulleys 4 4, so that each of the pulleys 4 4 is situatedbetween the two blades of the fork at one end of one of the arms 5 5,and so that when a pulley 4 is moved on the shaft 3, the arm moves withit, and that when the pulleys 4 4 are tightened to the shaft 3, theshaft can revolve freely in the holes of the arms. In the forks at theother endsof the arms 5 5, the pulleys 6 Gare placed revolvingthepulleys 4 4 on pins. Over every pair of and 6 6, one of the endlessIndia-rubber belts 7 7 is stretched. The diameters of the wheels 1, thepinion 2,

touch the surface of the impression-cylinder G, and that the speed ofthe belts 7 7 is just equal to the speed of the circumferenceof thecylinder 0. Figs. 1 and 4, extending from side to side, and fastened tothe frames S and S. Upon this bar 8 the polished metal guides 9 9 9 9,Fig. 4, are slipped, andmay be screws at places required.

India-rubber bands 7 j 7, is to be set, so that the rubber=bands, whenin motion, slide on the guides. In front of the cylinder 0, and abovethe same, a basket 10, composed of small metal strips, is placed toserve as an outlay table. Itis soconstructed, as to be lengthened andshortened, and it can be easily taken away and replaced. Inside thecylinder 0 are arranged for eachprinting Under each of the ing thepaper. To the shafts13'and 14 the levers 15 15 15 15 arefastened,.one.at each end of each shaft. Two pairsofthe levers 15 15,situated at the same end of .thecylinder,

one of which belongs to shaft:,13',- and*roneiito and through the arms aJ, so that the cam-shaft z will make the same turns as the main shaft J,j y 1 At the end of they cylinder 0, opposite thewheel WV, the spur H Uwheel 1, Figs. 1 and 5, is fastened to the: cylthe pinion2, which is 1andturn with it,

and the pulleys 4 4 4 are so calculated, that the India-rubber belts 7 7Above the cylinder G is bar 8,

tightened by setone of the guides 9 9 shaft 14, are connected by therods 19 19. To those ends of the connecting-rods 19 19 which Thegripershafts 11, and the discharge finger-shafts 13 13 and 14 14, areheld-in bearings in the webs of the wheels at either end of cylinder 0.The griper-shafts 11 11 project over their bearings in wheel 1, Figl 1,and are provided outside of Wheel 1 with double-armed levers 22 22, madein one piece with the shafts. To these levers are attached at one armthe friction-roller other arm the spring-rod 24. A spiral spring, woundover each of the rods 24, presses with one end against the guide 25,through which the spring-rod 24 goes, and with. the other end upon thehead of the rod 24, and so acts For the purpose of opening the gripersto receive the paper to be printed, and to deliver plane upon which thefriction-roller 23 runs, and so the gripers open. The cam 26 is drop bythe revolving cam 31, whichis fastened to and revolves with thecam-shaft z, and which acts upon the roller 30 attached to the cam-rod29 the latter is jointed to the cam 26. The cam 27 is fastenedstationary to the side frame S in such a position and with such a shapethat the roller 23 will run on to it, and cause the gripers 12 12 12 toopen when the end of the paper arrives under the rubber belts 7 7 7, andthat the roller 23 will run off and close the gripers again after thepaper is'delivered.

The discharge fingershafts 13 13, Fig. 4, project over their bearings inwheel W, and carry outside of this wheel the levers 32 32, fastened tothe shafts at one end and provided with a friction-roller, 33 33, at theother As long as. the roller 33 is in contact with the the ends of thefingers 21 21, to the endless India-rubber bands 7 7, and to follow themo;

tion of the paper, moving with the rubber bands 7 7 until the paperreaches the polished metal guides or ways 9 9 9 9; then the roller 33will leave the cut-out and the fingers 21 21 will be drawn back to thecylinder. The combination of the shaft 14 with shaft 13 causes the tipsof the fingers 2121 to describe such a way that they follow the motionof the India-rubber bands 7 7, or of the edge of the paper which ismoving with them. A little irregularity is corrected by the elasticityof the fingers 21 21. Under the cylinder, and attached to the rods 103and 109, are tapes, or elastic bands 108 108, Fig. 4, to hold the paperto the cylinder smooth and free from Wrinkles.

IV.The Inking Apparatus. The inking consists in the ink-fountain 37,

Fig. 1, with the iron roller 38, the composi-- tion dip-roller 39, thecomposition table-distributers 40 41 42, the ink-table 43, Fig. 4

the four composition form-rollers 44 44 44 44,

the two ink-cylinders 45 45, made of iron or hard wood, the twocomposition distributingrollers 46 46, and the small iron rollers 47 47.

In the drawing the dip-roller 39 is shown While the dip-roller 39 is incontact with the roller 38, this is turned so as to receive a thin coatof ink from the reservoir of the ink-fountain, which is 48, Fig. 2, andto which the ink is supplied, and so as to apply a narrow stripe of inkto the dip-roller 39. The thickness of the coat of ink, which the roller38 takes out of the reser: voir, can be regulated by the set-screws 4949 49, Fig. 2. Each of these set-screws acts upon one levers 50 50 50press the knife 48 more or less against the roller 38. The amount ofturn of the roller 38, and consequently the width of the stripe of inkput onto the dip roller 39, can be regulated from the feeders stand.When, as the bed B with the ink-table 43 is running forward andbackward, the ink-table 43 passes under the dip-roller 39, the latterwill drop and roll upon the ink-table 43 and give Thedistributingrollers and they divide it over the inkunder them.

The form-rollers 44 44 44 44, Fig. 4, take ink from the ink-table 43while rolling on the same; then give the ink to the ink-cylinders 45 45and take it back from them in a more equallydivided state; and thenapply the evenly-die I reservoir.

pieces of paper, and other strange bodies,

vided ink to the type or form while it'is passin g under them. Upon theink-cylinders 45 roll and vibrate the distributin g-rollers 46 46,connected with which are the iron-rollers Altogether the system ofrollers compiled over the form-rollers distributes and grinds the inkvery finely, and serves as a By this arrangement all dust,

mixed accidentally with the ink, will accumulate on the small ironrollers at the top, and

the composition-rollers 46 46 on top of theinkcylinders 45 45 vibrate.By this arrangement all composition-rollers in the system are moredurable.

The ink-cylinders 45 45 are held in stationary hearings in theroller-frames 51 52, which are firmly secured to the side-frames S andS; but; the bearin gs are so arranged that the cylinders 45 45 can beeasily taken out, when required. Upon the shaft of each ink-cylinder atoothed wheel, 53 53, Fig. 1, is fastened, by which the cylinder isoperated. These wheels gear into the intermediate wheels 54 54 which aredriven by the rack 55 fastened to the bed B.

Iheiformrollers 44 44 44 44 are held in adjustable bearings 56 56 56 56,so that they can be lowered and moved onto the ink-cylinders 45 45 whenthey become smaller in size by shrinking or wear and that they can bequickly and correctly adjusted in regard to their position to theink-table and form and to the ink-cylinders. The form-rollers 44 44 4444 are turned by friction by the ink-cylinders 45 45. The bearings 56 5656 are made with round stems, which fit in holes in the bearing-holders57 57 57 57. ()n the stems of the. bearings 56 are screw-threads cut andthe 7 nuts 58 58 screwed, by which either end of the form-rollers-may beraised or lowered. The bearing-holders 57 57 57 57 slide with groovesplaned in them on projections 59 59 of the roller-frames 51 52; and theycan be tightened by the set-screws 60 60. The nuts of the setscrews 6060 are tapped into the bars 61 61, which are slipped with their openholes between collars on studs 62 62. The studs 62 62 are riveted intothe roller-frames 51 52. Between the bearing-holders 57 57 and theset-screws 60 60 the plates 63 63 63, which slide on the studs 62 62 62,are placed to prevent the points of the set-screws 60 60 60 from beingpressed into the roller-holders 57 57 When one end of one roller is tobe moved on or off the corresponding set-screw only is to be loosened.When all the form-rollers are to be taken out the set-screws 60 60 ofone side have to be loosened and the bar- 61 lifted 06'; then the plates63 63 and the bearingholders 57 57 with the bearin gs can be slipped offendwise, and the rollers 44 44 may be easily and quickly taken out.

The distributing-rollers 46 46 receive their.

vibrating motions from the eccentrics 64 64 fastened to the cam-shaft z,and through the eccentric yokes and rods 65 65, the double-armed levers66 66, the connecting-rods 67 67, and single arms 68 68. The eccentricyokes and rods 65 65 are made in one piece, andthey are jointed to thelower arms of the double-armed levers 66 66, which vibrate on the pin 69of the bracket 7 0. frame S. Each of the connecting-rods 67 67 jointsthe upper endof the upper arm of one.

of the double levers 66 66 with the upper end of the opposite single arm68, and causes the same to vibrate on the pin 71 of bracket 72, which isbolted to the side frame S. Between the levers 66 66 and 68 68, and inthe slots of.

the roller-frames 5152, the vibrating rollers 46 46 are held. Thisarrangement isimplifies 1 the laying in of the rollers very much,because no cross-heads or collars have to be attached to them, as inpresses which have levers only on one side to vibrate the rollers.uting-rollers 40 and 42 are vibrated from the eccentrics 73 73, whichare fastened to the camshaft 2 also, by the double-armed levers 74" y 74and the single levers 75 75, through similar means and in the samemanner as the rollers 46 46. The bearings in whichthe rollers 40 41 i 42are held are like thebearings of the formrollers, but open on top andonly adjust-ablein height. The dip-roller 39 is held in bearings in thevibrating arms 7 6and 77, Fig. 2, which are fastened to the shaft 78.The shaft 7 Sis held in hearings in the side framesS and S. The rod 79is connected "at one end with the arm 76, and is providedwith the roller.80 at y the other end. Near the end with the roller 80, the rod has along hole, in which it is guided on the pin 81 which is fixed to theside frame S. The cam 82, which is firmly secured I to the main shaft J,acts upon the roller 80,

and has such ashape and such a position that it causes the dip-roller39, at right times, to come in contact with the fountain-roller 38, andto leave this to roll on the ink-table43. The ink-fountain roller 38 iscaused to turn, when in contact with the dip-roller, by the cam 83,which is firmly secured to the main shaft J, at the end, projecting overthe bearing in y The cam 83acts upon the roller i 84, which is attachedto the lever 85. The lever 85 is fastened to the shaft 86, outside of iI the side frame S. The rod 87 connects the lever 85 with the insideratchet-wheel 88, which] is put on the ink-fountain roller 38, and open:

side frame S.

ates the same. The shaft or axle86 is held in a long bearing in the sideframe S, and the lever 89 is fastened toit "inside of the side 1 frameS. Through the rod 90, the lever 89 is 1 connected with the lever 91,which is keyed to. the shaft 92 inside of the sideframe S. The shaft 92is held in a long bearing in the side The bracketTO is bolted to theside V The distribi frame S. Outside of the side frame S thehandle-lever 93 is fastened to the shaft 92. From the lever 93 theink-fountain roller 38 may be turned by hand.

V.--Arrangementfor Double Rolling and Single Printing.

For fine work it is sometimes required to let the bed with the form runtwice forward and backward under the ink-roller. For this purpose I havearranged my press with a mechanism which, when in operation, causes thefeedboard F, with the paper, to remain in the position off of thecylinder 0, while one set of gripers is about to close, so that thesegripers cannot catch'the paper. The second set of gripers will find thefeed-board and the paper in the right position to take hold of the paperwhen they are going to close. In case double rolling is wanted, Iprovide only one (either one) of the two printing-surfaces of thecylinder G with a blanket, and make only this surface ready forprinting; so that the surface not used is about the blanket thicknesslower than'the other, and the form can pass freely under it. To preventthe feed-board F from moving toward the cylinder when that set ofgripers is going to close which is not to be used, the lever 21, Fig. 1,is fastened to the shaft it outside of the frame S. To the lever u therod 94 is attached at one end, and the other end is provided with theroller 95, and guided by means of the pin 96, and the cam 97 attached tothe projection of the shaft of the cylinder outside the side frame S.When the feed-board moves (311' of the cylinder, the lever u and the rod94, with the roller 95, move downward; when the feed-board moves to thecylinder, these parts move upward; but that part of the cam 97 which islarger in diameter touches the roller 95 when in its lowest position,and prevents it from moving upward, and consequently the feed board frommoving to the cylinder. The cam 97 can be fastened by the screw 99 insuch positions that the larger part of the same will be in contact withthe roller 95, when those gripers are going to close, which are notwanted to catch the paper.

The smaller part of the cam 97 never touches the roller 95, and is sosituated that the roller 95 can freely rise; hence the feed-board withthe paper can move toward the cylinder when that set of gripers is goingto close which belongs tothe printing-surface in use.

What I claim as my invention, and desire to secure by Letters Patent,-is-' c 1. The hangers O, in combination with the connecting rod N,having on its end the spring 107, and the double-armed lever L ending inthe female stop-and-start tooth f, substantially as and for the purposeset forth.

2. The cam u on the'cam-shaft z, in combination with the cam-rod v, theelbow-lever s, the rod 10, arms a and A, and feed-board F, for thepurpose set fort 3. The shaft 14, in combination with the shaft 13,operating substantially as described, to cause the tips of the fingers21 21 to follow the motion of the India-rubber band, in their descent.

4. The mode of vibrating rollers longitudinally, by laying them betweentwo vibrating arms, the one at one side and the other at the other sideof the press.

5. The adjustable bearings 56, in combination with the bearingholders57, the bars 61, and the set-screws 60, substantially as and for thepurpose set forth.

6. The elastic-bands or tapes 108 108, Fig. 4, under the cylinder,attached to the rods 103 and 109 for the purpose of holding the paper tothe cylinder smooth and free from wrinkles.

7. The arrangement by which the blankets and the tympan-sheets arefastened to the cylinder, consisting in the clamping-bars 114 114, Fig.4, and 115 115, and the blanket-winders 110 110, with the hooks 112 112,or similar devices, for holding reglets around which the blankets ortympans are laid.
